Pork butt carnitas: crispy outside, tender inside

Pork is technically safe to eat at 145°F, but that temperature does nothing for carnitas. Connective tissue starts to dissolve around 170°F, and collagen fully melts near 203°F. Pull the pork before it hits that range and you get tough, chewy meat no matter how long it cooked.

According to ThermoWorks, keeping the cooking fat at around 200°F to 220°F maintains a consistent environment for collagen melt. That is why a low oven and a fat-based braise work so well together. The fat surrounds the meat and holds a steady temperature without drying it out.

Set your oven to 275°F. At that setting, the fat in the pot stays right around 200°F, which is exactly where you want it for the slow cook. A higher oven temp pushes the fat too hot and can tighten the meat fibers before the collagen has time to melt.

Use a heavy Dutch oven or deep roasting pan. Add enough lard, rendered pork fat, or neutral oil to come at least halfway up the pork pieces. You are not deep frying. You are creating a stable, even heat bath that cooks the meat gently for 2 to 3 hours.

This method works on a bone-in or boneless pork butt. Cut the butt into 3 to 4 inch chunks before cooking so each piece heats evenly and you get more surface area for crisping later. Season generously with salt, pepper, cumin, and dried oregano the night before if you can.

Bob once skipped the overnight salt and wondered why his carnitas tasted flat. Flip's fix was simple: season early, and the salt has time to work into the meat before the fat ever hits the pan.

1. 1Cut pork butt into 3 to 4 inch chunks and season with salt, cumin, oregano, and pepper.
2. 2Place the chunks in a Dutch oven and cover halfway with lard or neutral oil. Add a halved onion, a few garlic cloves, and a bay leaf.
3. 3Set the oven to 275°F and cook uncovered for 2 to 3 hours.
4. 4Start checking the internal temperature at the 2-hour mark. You are looking for 200°F to 205°F in the thickest piece.
5. 5Pull the pork from the fat and let it rest on a sheet pan for 10 minutes. Shred or pull it into large chunks.
6. 6Crank the oven to 400°F. Spread the pork in a single layer on the sheet pan and roast for 15 to 20 minutes until the edges are golden and crispy.
7. 7Serve immediately. Carnitas lose their crisp fast, so get them to the table while they are hot.

Do not guess by color or how easy it is to poke with a fork. Use a probe thermometer and check the thickest chunk. The target is 200°F to 205°F. At that range, the collagen has melted into gelatin and the meat will pull apart with almost no effort. Below 195°F, you will still hit some resistance.

Total cook time from oven-in to crispy finish runs about 2.5 to 3.5 hours depending on how large your chunks are and how your oven runs. If your oven runs cool, the pork may need an extra 30 minutes. Check the pork butt bark guide for more on reading pork butt doneness by feel and temperature together.

The most common problem is pulling the pork too early. If the meat shreds but still has chewy spots, it likely came off at 190°F or below. Put it back in the fat bath and give it another 20 to 30 minutes. Check the temp again before moving to the crisp stage.

Soggy carnitas after the 400°F finish usually means the pork was crowded on the sheet pan. Steam builds up between pieces and prevents browning. Spread the chunks out so each piece has at least an inch of space around it. If you have a lot of pork, use two pans instead of one.

• Meat is chewy: internal temp was too low. Return to the fat bath and cook to 200°F to 205°F.
• Carnitas are soggy: too much fat left on the meat or pieces were crowded. Pat dry before roasting and spread them out.
• Meat is dry and stringy: the oven ran too hot or the pork overshot 210°F. Add a spoonful of the cooking fat back over the meat before serving.
• No crisp after 400°F: the sheet pan was lined with foil and the fat pooled. Use a bare pan or a wire rack over a sheet pan so the fat drips away.
• Bland flavor: seasoning went on right before cooking. Salt needs time. Season at least 2 hours ahead, overnight is better. See how we season pork butt for bark for a deeper look at dry rubs.
